Abstract

Buluş, aşağıdaki işlemleri içeren bir stereolitografi işlemi ile üretilecek olan üç boyutlu bir nesne (1) için bir destek yapısının (2) tanımlanması için bilgisayar tarafından uygulanan bir yöntemdir: üç boyutlu nesnenin (1) desteklenmesi için bir birinci yüzeyin (3) ve birinci yüzeye (3) bakan ikinci bir yüzeyin (4) tanımlanması; yüzeyler (3, 4) arasında uzatılmış destek elemanlarının (5) tanımlanması; destek elemanı çiftlerinin (5) tanımlanması; her bir destek elemanı çifti (5) için, çiftin iki destek elemanını (5) birleştiren uzatılmış bir takviye elemanının (6) tanımlanması. Destekleyici elemanların (5) çiftlerinin tanımı aşağıdaki işlemleri içerir: her destek elemanının (5) bir referans noktasının (7) tanımlanması; referans noktalarına (7) köşeleri olan bağlantılı bir asiklik grafiğin (8) tanımlanması; grafiğin her kenarı (9) için, kenarın (9) uçlarına karşılık gelen iki destek elemanı (5) içeren bir çift destek elemanının tanımlanması. Destekleyici elemanların (5) çiftlerinin tanımı, bağlantılı asiklik grafiğin (8) her 1 derecesine sahip tepe noktası için ilave bir destekleyici eleman çifti tanımlamanın daha ileri işlemini içerir, ilave çift, 1 derecesine sahip tepe noktasına karşılık gelen bir birinci destek elemanını (5) ve birinci destek elemanına (5) bir kenardan (9) bağlı olmayan ikinci destek elemanını (5) içerir.The invention is a computer-applied method for defining a support structure (2) for a three-dimensional object (1) to be produced by a stereolithography process comprising the following operations: a first surface (3) and a first surface to support the three-dimensional object (1). (3) defining a second facing surface (4); defining the elongated support members (5) between the surfaces (3, 4); defining the support member pairs (5); For each support member pair (5), defining an elongated reinforcing member (6) connecting the two support members (5) of the pair. The definition of pairs of supporting elements (5) includes the following operations: defining a reference point (7) of each support element (5); defining an associated acyclic graph (8) with vertices to the reference points (7); defining for each side (9) of the graph a pair of support members comprising two support members (5) corresponding to the ends of the edge (9). The definition of pairs of supporting elements (5) includes the further process of defining an additional supporting element pair for each vertex with degree 1 of the associated acyclic graph (8), the additional pair includes a first support element (5) corresponding to the vertex of order 1 and It includes the second support element (5) not connected to the first support element (5) at an edge (9).
